- Steam lists in-app purchases but we have no detail on them. Small caution applied.
The value story
It has never been cheaper than $1.46. That was August 2026. 17 discounts in the 10 years on record. They run about 60 percent off, roughly 13 weeks apart. Today's $1.46 at 79 percent off matches the lowest price in the record.
On value it sits in the top 29 percent of its genre. Among the games that feel like it, Sentinels of the Multiverse ($1.99, scores 80) beats it on value, while it beats Business Tour - Board Game with Online Multiplayer(大富翁) (free, scores 5).
Of the 391 Steam-purchase reviews this site sampled, none come from buyers who refunded the game, sampled from reviews written March 2020 to August 2026.
Finishing takes 2.2 hours; clearing it takes 11, which is 4.9 times the campaign.
Valve rates it Steam Deck Verified, and at 2.2 hours it is short enough to finish on one.

Nunca hay nadie para jugar así que lo del multijugador no tiene sentido. Es un juego bonito pero que no hay por dónde cogerlo. Igual jugado con gente en casa gana mucho más, pero en ordenador pierde la mayoría, por no decir toda su gracia
can't make private lobby's for friends and I. I have to go to solo then main menu then try to go online. WE had 5 players and 2 people got assigned as ghost. What the main ghost put down wasn't showing up on the second ghosts screen. we also don't know who is who when joined. the character icons are gone when joining a lobby. Also it's always the first person on the list for the final round. TOO MAN BUGS!!!
